and useful Improvement in Driving Mechanism for Railway-Cars, of which the following is a full, clear, and exact description.-

This invention is designed especially for use in connection with selfpropelled railway cars.

It relates to the mechanism, associated withone of the swiveled trucks of such a car,

for transmittin motion from a motor on the car to the whee s of s uch truck.

In the drawing Figure 1 is a plan view of the mechanism embodying this invention,-- the top member of the casing being removed and a portion of lthe casing broken away. Fig. 2 is a sectional side elevation in the plane indicated by line 2-2 on Fig. 1, and a central longitudinal section of the associated ,truck,a portion of the casing D being broken away. Figs?) is a transverse sectional View in the lane indicated by line 3-3 on Fig. 1, andp showing the driving shaft 'rn vertical section aportion of the lower casing member d2 being broken away so asto show one of the caps F which forms a part of the bearing of the Y axle A. In Fi s. 2 and 4 parts bf. the swiveling truck are s own in dotted lines. Fig. 5

is a sectional side view ofy oneof the bearings of the axle B carried by the frame member d, said section being in the'plane indicated by line 5--5 on Fig.

Referring to the parts by letters A and B' represent 'the two axles, which are associated with, and support, in the usual way, one of the swivel trucks C of a railway car; and a and b represent the wheels, which are respectively made fast to said two axles.

D represents a frame, in the forni of a casing, in which said axles are rotatably mounted, and which serves to maintain them 'in parallel relationship and at an invariable distance apart; and t is casing also incloses and supports the mechanism by which said two ax es are rotated.

The casing D is made up of three members d-dfd2- The member d is provided, `near its ends, 'with the upper halves of the bearings F--F for the two axles. The lower halves F"`of said bearings are secured by bolts d? to the member d. The casing niem- Fig. 4 is an end view,-

T e shaft E is mountedy near its ends in' bearings J and K respectively; the upper lhalves of which are fori'ned in the casing member d. The lower halves of said bearings are formed by caps jand 7c which are Secured by bolts or Aotnerwise to the under side of the casing member. d. `This shaft; carries, at its ends, the beveled gears e-e for engagement with the beveled lgears a2 b2, which are secured respectively to the two axles, and are located, the one on one side and the other` on the other side of the axis of shaft E, whereby the rotation'of said shaft will drive both axles-in the saine direction. The other shaft G is also mounted in bearings M and N, which are kwholly su ported by, the casing meinber d.' In te construction shown the lower halves of said Y .bearings are formed inthe top1 of the casing member d, while the upper alves of said bearings are caps secured to said member d. This shaft projects out through the en'd of said casing; and the protruding end thereof is connected with a driving shaft H by ineens of a universal joint P. VBoth of the axes of this universal joint are in. the sane trans- Vverse vertical plane with the axis O of the king bolt upon which the truck C swivels.` The turning of the truck, therefore, upon its axis, does not interrupt or affect the transmission of motion to shaft G frein the driving shaft H, even though said driving shaft receives its motion from a motor upon a car supported upon said truck.

t has not been thought necessary to show the car or the motor, because they are no vpart of the present invention; nor has it een thought necessary to show the universalV joint which it would probably be necessary to use4 for connecting lshaft HI with some longitudinal shaft on the car driven by the motor.

` The shaft G is provided with collars g?,

which prevent endwise inoveinent of said shaft 'within its bearings. Two gears g--gl of 'different diameter are secured to shaft G within the casing. An adjacent portion ef' of shaft E is made square; and upon this squared portion is a sliding sleeve lt carrying two gears r--r ol' different diameters, and adapted to engage respcctiv ely with the rotat' gears g p. This sleeve R is provided with an annu ar groove r2 into which project pins t carried by a forked arm t,-said arm bein secured, within the casing, to the lower en of an operating shaft T, which is mounted in a suitable bearing d5 in the casing member d. By operating shaft T, the sleeve R is moved longitudinally in either direction so that its gears may severally engage with the gears g or g as required to change the ratio between the speeds of shaft G and shaft E.

It will be seen from the foregoing descri tion that the mechanism within the casing is supported wholly by the casing member d; and, therefore, said mechanism may all .be mounted and adjusted in said casing member before the same is connected up with the axles; The casingmembers d d2 ma be removed in order 'to get at the inc osed mechanism for adjustment or repair without changing the operative relationship of the inclosed mechanism.

Having described my invention, I claim:

1. The combination with a swiveling car truck, the two axles upon which it is supported, and wheelssecured to said axles, of a frame. which rests u on and is supported by 'said axles and has bearings in which the axles rotate, a lon 'tudinally extended shaft which is mountedl in bearings upon said frame, mechanism supported bysaid frame for transmittin motion from said shaft to one or both of t e axles, a driving shaft, and.

a universal joint connecting said shafts and having its pivots in substantially the same transverse vertical plane as' that which contains the axis of the truck king bolt.V

2. The combination with a swiveling car truck, the two axles upon which it is suported, and wheels secured to said axles, of .a rame whichrests upon said. axles and has bearings in 'which 'they rotate, a longitudinally extended shaft mounted in bearings upon said frame and having beveled gears secured to its end, mechanism for rotating said shaft, andbeveled gears secured respectively to said axles on opposite sides of the axis of lsaid shaft andin mesh withgthe beveled gears thereon, and mechanism by which motion may be transmitted to said shaft from a motor on the car to which said truck is swiveled.

3. The combination with a swiveling car truck, the two axles upon which it is su ported, and wheels secured to said axles, oY a casing which rests upon said axles and has bearings in which Ithey rotate,-said casing being composed of separable prts, a longitudinally extended shaft W 'ch projects through the casing wall and is mounted in bearings within the casing, `mechanism for said shaft, and mechanism within the casmg for transmitting motion from said shaft to both axles. I

4. The combination with a swiveh'ngrcar truck, the two axlesupon which it is sup-- ported, and wheels secured to said axles, of A a frame which rests upon said axles and has bearings in which they rotate, a longitudinally extended shaft which is mounted in ported, and wheels secured to said axles, of a .casing consisting of a middle member which rests upon said axles and carries bearings ink which they rotate, a removable bottom sectio n and a removable top section, two parallelshafts within the casing mounted in bearings Vsupported wholly by the middle section,-one of said shafts being extended out of the casing, mechanism.within the casing for transmitting motion from that shaft to the other shaft, mechanism for transmitting motion from the last named shaft to both axles, a drivin shaft outside of said casing, and a universa joint connecting said driving shaft with the projecting end of the shaft first mentioned, said universal joint being located substantially as described where a prolon ation fof the axis of the truck king bolt will intersect said universal joint centrally.

6. The combination with a swiveling car truck, the two axles upon which it is sup ported, and wheels' secured to said axles, of a casing ,which is secured upon said axles and has bearings in which they rotate, `the longitudinal shaft G mounted in'bearings within said casing and having one end protruding therefrom, two gears -ixedto said .shaft within the casing, the longitudinal shaft E mounted in bearings within the casing, two

'beveled gears secured to its ends respectively, a sleeve slidable u on the last mentioned shaft but com elle to rotate with it, two ears fast to said sleeve, an operating spinde rotatably mounted in the casing and projectin from tqlie outside into the casing, a'forked ever secured to the inner end of means which compel it to rotate said spindle for operating said sliding sleeve,

and beveled gears secured to the axles and meshing with the beveled gears upon said In testimony whereof, I hereunto affix my signature in the presence of two witnesses.
